You can also use QT5 in macOS
### Linux
`pip install pywebview[qt]` should take of QT dependencies. If it does not work or you would like to use GTK, you may try these recipes.
[PyGObject](https://pygobject.readthedocs.io/en/latest/) is used with GTK. To install dependencies on Ubuntu for both Python 3 and 2
``` bash
sudo apt install python-gi python-gi-cairo python3-gi python3-gi-cairo gir1.2-gtk-3.0 gir1.2-webkit2-4.0
```
For other distributions, consult the [PyGObject documentation](https://pygobject.readthedocs.io/en/latest/getting_started.html)
Note that WebKit2 version 2.22 or greater is required for certain features to work correctly. If your distribution ships with an older version, you may need to install it manually from as a backport.

[PyQt5](http://pyqt.sourceforge.net/Docs/PyQt5/index.html) is used with QT. `pywebview` supports both QtWebChannel (newer and preferred) and QtWebKit implementations. Use QtWebChannel, unless it is not available on your system.
To install QT via pip
``` bash
pip install pyqt5 pyqtwebengine
```
To install QtWebChannel on Debian-based systems.
``` bash
sudo apt install python3-pyqt5 python3-pyqt5.qtwebengine python3-pyqt5.qtwebchannel python-pyqt5 python-pyqt5.qtwebengine python-pyqt5.qtwebchannel libqt5webkit5-dev
```
To install QtWebKit.
``` bash
sudo apt install python3-pyqt5 python3-pyqt5.qtwebkit python-pyqt5 python-pyqt5.qtwebkit libqt5webkit5-dev
```
